Nezuko's original personality as a human was that of a kind and caring girl who thought of others before herself, much like her older brother, Tanjiro. Additionally, she was a responsible elder sister to her younger siblings and often put their needs before her own.[8][9] Nezuko is, however, not afraid to get in harm's way, protecting her friends from demons even after being returned to a human state. It is also shown that Nezuko's humane, laid-back demeanor supports this fact after Tanjiro apologizes to her.[10]
